Thumbs up One Possible Solution

Ahhh.... there you are! There was I trawling though the vBa site wondering whether I'd been banned for raising a problem because I couldn't find my posts

We've done some research and testing on our server on this one, symptons were as described in an earlier post - blank screen, but file was within PHP upload limits and seemed to upload OK. I can confirm a theory put forward by Brian (vBa) on this, it IS to do with the overall PHP memory limits if you're running GD image processing.

We were testing on the default PHP memory limit of 8MB with .jpg image files around the 250KB physical size but something like 1000x800 pixel resolution, what seemed to be happening was that the GD component within the PHP processor was crashing out trying to resize it and giving the blank screen. Upping the overall PHP memory limit has solved this problem. The only trouble is I can't tell you what the limit should be for various file sizes!

Hope that helps somebody, this one has been bugging me for weeks. At least we are getting to the root of it and now know a lot more about what can cause these blanks screens.

Cheers
