Automatic Re-sizing of Images

In most cases, the Discussion Board is able to resize pictures from you "on the fly", and without any intervention by you.

The maximum size that can normally be displayed on the board is 540 x 540 pixels.
Anything smaller than that is simply displayed "as it is", with no intervention by the board software.

If an uploaded picture is larger than that, and won't fit into a 540 x 540 pixel "box", the software intervenes, and scales the picture so that it does fit into 540 x 540.
For example, uploading a 600 x 400 picture would cause the software to intervene, and re-size it to 540 x 360.

That situation is maintained all the way up to uploaded pictures of 3264 x 2448.  That is, to the biggest possible output from an 8 Megapixel camera.

It is simply not possible for us to do an automatic re-size of pictures larger than that, and these are becoming increasingly common as we start to see 10 and 12 Megapixel cameras in the shops.
In any case, it is probably not desirable.  As photos get larger, the time to upload them increases, using your bandwidth and also causing delay - a large picture can take several minutes to upload.

Better for larger pictures, and mandatory for those over 8 Megapixels, is to re-size the picture on your own computer before uploading it.  There are several ways to do this, and we discuss them in the next two sections.

 

For the moment though, the message is this:-

  • If your picture is small, just upload it, and we will attend to it.
  • For larger pictures, up to 8 Megapixels, you might like to consider resizing them before uploading.
  • Pictures above 8 Megapixels must be resized before uploading
