Vbulletin Image resizer not working properly

[richy96]

HI all

First I am not sure what image resizer my vb3.7.0 site is using, In ACP Image options it says GD but is that only for thumbnails?

I can't seem to find any other settings in ACP that control the image resize options for User Album Pictures and don't think it is a product installed (like TCattitude Image Resizer)

I have included a screenshot so hopefully someone can say which resizer this is

Anyway I have two problems at the moment

First Problem : The resizer does work but seems to give up on larger images

I tried resizing the same jpg image in Paintshop Pro and then attempted to upload it

The results I got was

1296 x 1944 336Kb jpeg uploaded and resized ok
1575 x 2362 415Kb jpeg uploaded and resized ok
1750 x 2624 522Kb jpeg failed
1944 x 2916 1.1mb jpeg failed

So somewhere between 415Kb and 522Kb it is giving up. When upload fails basically I don't get any error (unless there is one in a log somewhere that could shed some light on this problem) it just sits there for ages then says server failed to respond

I think gifs may have problems at different sizes but haven't thoroughly investigated this yet.

Is this a server issue or a vbulletin issue and how do I fix it?

I am not sure if we had this problem before I moved my site to a dedicated server last November. That may be a red herring.


Second Problem : how do members upload photo's from iPhones? I have members with Android phones who can upload images OK but I need to get this working for other smartphones as so many people are using them nowadays

Cheers
