I don't think the people here are unhelpful intentionally - i think part of the problem may be that there is a substantially higher amount of people looking for help than people who are qualified to give help, and those people have a life outside of osTickets - that's my rough estimation at least.
In either event, you can't expect a response from a software which has no support unless you subscribe to paid support (which, I think, from the description, gives you direct access to the developers)
@[deleted] Thank you, yes. We would love to spend more time on the forums and we do so when we can, but we give the software out for free, and we have families and bills to pay, just like anyone else.
We provide the forum as a service, in hopes the community of osTicket users will help each other out, and then we jump in when we have the time to do so.
There are some folks around here who are great about helping out, but I haven't seen a lot of them around lately, I can only assume life happens.
There is always commercial support available, but we only have so many hours that we can "give away" and most of those are spent on development.
@[deleted] as to your problem, it does sound like a resource issue, either in the amount of memory that the server is consuming during the upload process, or the maximum execution time, or max upload size.
After you made the changes to your php.ini file, did you restart your web server?
Do you have the Zend extension/Zend memory manager enabled? I can't imagine a PHP installation that doesn't, by default, but then, it's been ages since I've dealt with IIS. If not, do so, it will make a big difference in efficiency of memory usage. I have particularly found this to be true with file handling.
