Image Manager addon

[destruxon]

hi all
My install is zc 1.5.0, php 5 & mysql 5, using IM 1.9 even though it says 1.7 in admin is this right? My install is in a sub folder and my pics reside in /images/large/gifs/ folder. I dont use small or medium pics, the main reason for install was the watermark and tidy up utilities :) All seemed to install ok, i can view unattached files ok but when i go to view attached files which in my test site which i only have about 100 pics, i get the error message:

Fatal error: Allowed memory size of 73400320 bytes exhausted (tried to allocate 80 bytes) in /mnt/vol1/home/h/i/*****/public_html/zen*****/adm****/includes/functions/extra_functions/function_image_manager.php on line 140

which i believe from previous posts that its a server memory error ? but should this do this with only 100 large pics? they are sized 500 x various.

When IM installed it created the folders listed below is this right?

Messages
Watermarks are present for: medium, large.
Folder created: /mnt/vol1/home/h/i/*****/public_html/zen****/images/medium/large/gifs/
Folder created: /mnt/vol1/home/h/i/*****/public_html/zen****/images/large/large/gifs/
Folder rights are sufficient

If i view one pic by product id it shows ok with all links, but even thought its in the large/gifs/ folder its showing as a small image saying med & large images are missing? Any advice would be appreciated, its a great plugin and would like to get it working right. Is the problem related to me having large pics only and them beingg there before install?

cheers dessy
