Hi busybee,
Welcome to the agora cart forum!
AgoraCart is written in perl, rather than php, so a php.ini implementation will be of no help.
The official recommended approach is to have the client optimize their images, or to use an FTP program (FileZilla etc) to upload the large images to the store/html/images directory. As I remember it, the max bytes is 131072, which is more like 130k, but that is between all images, so I suppose if you have 3+ images it would constrain the size that each could be to <50k
If neither of those things is possible,
the line you are looking for is in the library/cgi_lib.pl
If you choose to modify the file, be sure to make a backup, and to download and upload in ASCII mode.
