    Another quick video showing how to resize images, and post them on the upgraded software

    I will be imposing stricter image controls after the upgrade so no 3000x2000 images please :))

    The limit is set on 1024kb which is more that large enough, please try and use a maximum size of 1024px x 768px

    does this mean that I can no longer resize in Picasa and import as i do now or will I have to re-educate myself?

    Picasa is just fine (i use it myself) as is any other similar application. The resizing bit is aimed at those who post mega images  :)) and to show how simple it is.

    I normally resize to 800x600, 640x480 can be a bit small.

    thanks Cynric, watched the video after my posting and that seemed to put my mind at rest.

    Slightly off topic, but would I be right in thinking that You tube type vids will take up little or no space as they are hosted elsewhere ?

    no space as it is just embedded, not saved into the site

    Still on the subject of videos, can I embed a video like any other file on here?
    And if so, how do I compress it? - I have a video to share but it's 38.9Mb and straight off my camera . . .

    Hi Guv'nor
    Thanks for letting us in on the secret of how to re-size images and just to prove I have been successful here is an image of my first tank wagon I made from a Slaters kit. I have to admit I got as far as constructing and priming the tank, making the underframes and stalling at finishing with the strapping and transferring . The credit for this goes to Rob Helson who also did some fantastic weathering too.....
    Kind regards

    Guidance please. How do I put a video on here? I've got some phone footage of three 37s pulling 40 16 tonners up Aberbeeg; it might bring a smile in certain parts of the school room! The video is a bulky 172Mb.

    I find putting video's on You tube then sharing the link works well.

    Thank you Ian, that will be today's new experience!

    Yes, host your video on YouTube or similar, then click the film strip symbol on your WT reply box & embed the URL from your YouTube video :)

    Thank you Phil, I'll have a go after I have reassembled some of Aberbeeg back into the shed. At the moment it looks like a bomb has gone off after the return from the Leeds show.

    I have been uploading images to a topic which are clearly being resized on upload. I can appreciate there being a limit to the file size of the image being uploaded e.g. the 1024kb mentioned above, however why is there a need to resize a 3000 x 2000 image if it is within the 1024kb limit. A simple answer might be the forum software is unable to display images larger than the 1024 x 768 size quoted above.

    The problem I am facing is in my case these are technical drawings which a user needs to be able to zoom into to read the dimensions which they are currently unable to do.

    Adrian will be able to provide the full answer regarding allowable image sizes. One option would be to upload a pdf file of the drawing - they can be larger files but viewers have to open them to see them so not as user friendly as image files.

    Thanks. Unless PDFs have heavy compression they tend to be too large to upload.

    It would be really useful if someone could describe the processes an images goes through on upload. I can them (hopefully) adjust accordingly.

    My apologies for the delay in replying - I'm slowly catching up on posts after a couple of weeks holiday.

    The software should limit the size of any images to a maximum of 1500px x 960px and resize appropriately if any larger. This has been refined over the years as a suitable compromise for those on a slow internet connection to provide a reasonably responsive page loading and yet also allow a reasonable resolution to view fine detail in the photos.

    Attachments in general are limited to 10Mb is size - unlike images they are not displayed inline on the posts but appear as a download link in the post. So the larger attachments do not slow down the loading of the pages but the end user can make a conscious decision to download the file by clicking on the link. This includes pdfs documents.

    The thing with pdf documents is that it was originally designed as a Portable Document Format (hence pdf) and if you open them in a text editor you can see internally it has it's own text markup language and vector imaging system which can be compressed. So when you convert a word document to a pdf then it can be compressed by a significant amount. Unfortunately it cannot convert images, jpeg, png etc. so they are simply embedded in the pdf, this means that when you convert an already highly compressed image file to a pdf it is unable to compress it any further so a pdf from an image is often larger than the original image as it has a little of the pdf markup wrapping around the image.

    So if the generated pdf is less than 10Mb in size then you should be able to attach it. Alternatively I would look at the specific application you have used to generate the technical drawing - unless of course they are just photos of a paper drawing. If it's a drawing package then can you export directly to dxf or pdf format? i.e. skip the image stage - frequently these will be smaller than the image file and are amenable to compression. Finally if it exports to a different format then please let me know which format and I can look into tweaking the attachment settings to allow other formats, I've done this previous for SketchUp files (*.skp).

    Thanks for the detailed reply.

    I have discovered, as you suggest, that if I resize images to <= 1500px I normally get away with it. My objective was to ensure that dimensions in the image were still readable which can be helped by splitting a largish image into several fragmented ones. Unfortunately the drawings are not available in vector format.

    Overall I was happy with the compromise.
