Error 500 - Internal Server errors when uploading via Batch or HTTP

[Humpa]

I am able to upload some images, but I normally get an error 500 - internal server error message.
I verified that my "albums" folder and sub-folders are set to 755.

cpg 1.4.14
max_execution_time is 50seconds
upload_max_filesize is 20M
post_max_size is 8M
memory_limit is 40M
file_uploads is On

I have read thru the faq's and various threads, but haven't seen anything that seemed pertinent.

I know php, so even any hints at what to try or look at would be appreciated. Though I'm about ready to simply create my own gallery - I'd just like an easy way to show my pics and to also allow for comments.

Thanks

Just an update.
I have the image width for intermediate pics set to 900 and I can upload files that don't need to be resized. I just batched 96 pics that were 900px max and it worked fine.
And I can upload a 115kb, 1000px pic. But a 300kb pic gives me the 500 Internal Server Error.

So I can at least use the gallery. If I want fullsized pics available, I can at least do it manually (replace/ rename files and update the width/height in the database)

Review the server logs to find what is wrong - an internal server error is what the name suggests.

I just tried uploading three pic's (about 1mb and 3000x2000px and 2 with firefox and 1 with IE) and I'm not sure what to make of the normal access logs

It doesn't seem to tell me anything.

Any idea what I should be looking for? Or is there a file I can edit to get more info and try to determine where I'm running into problems?
Also, I deleted my .htaccess file in the root in case there was something in there that was conflicting.

Access log won't tell you what the error is; that's what the error log is for.

It is a 1and1 hosted site so that's all I have access to.
