[thelist] PHP File Upload, Image Resize, Gallery Articles or Tuturials

With large files it's also nice to get some idea of progress.  This is 
something I ran into a while back, tested, nice:

If phpthumbnails does not work, take a look at ImageMagick and 
'convert'. It's got lots of intriguing image manipulations options way 
beyond creating thumbnails.  With the image galleries that I play with I 
use it to create varying sizes of uploaded images.

Question back at y'all - I also have PHP scripts to upload PDF documents 
- regarding limits, on one of the sites (hosted) the script will upload 
up to about 2MB, then fails (probably the same limit with all documents, 
images, etc);  the hosting service said they have no limits in place, 
but I'm wondering if there is a 'default' in place that I can override? 

This is good information.  -Bob
