First off, great class and amazing functionality!
But, I have a problem when uploading and resizing a particular image which causes a "white screen of death"- there is no html or source code. I am guessing it is to do with the image (pixel) size but I don't remember seeing any restrictions mentioned. All other (smaller) images have worked , no problem...
The code generates three images of different sizes, but they all use the same parameters as the snippet below.
$handle->file_overwrite = true; $handle->file_auto_rename = false; $handle->file_new_name_body = $_SESSION['s_pairid'].'_bg';// NOTE use '_' not '-' in names $handle->image_resize = true; $handle->image_ratio_crop = true; $handle->image_y = 187; $handle->image_x = 280; $handle->image_convert = 'jpg'; $handle->jpeg_quality = 90; $handle->process("$pathtorootshort/pairs/");I did an 'echo $handle->log' and got this for the large (2816x2112px) img:

I am doing a header redirect after processing and get the usual php warning messages about not being able to do a redirect (due to writing log to screen) ONLY after the smaller image upload.
Hope you can help! (I can send you the image if you want.)
Thanks

You need to raise the PHP memory limit, usually in php.ini. On shared hosting, you probably can't edit your php.ini, so you can try the following, although it will work only if the hosting company allows it, which they usually don't.
You can add this in your script:
Or in a .htaccess file:
If the above doesn't work, ask your hosting company.
