Postie Size limits

Every now and then, when I send an e-mail to the e-mail address I set up for posting, the e-mail gets lost. When I click on a€?Run Postiea€? under the Configure Postie menu I receive the following message:

Connecting to mail.yoursite.com:110 (pop3))
Mission complete, message 1 deleted.
[email protected] is authorized to post as the administrator
Email has following attachments:text plain

__________________________________________
The image gets copied/placed in the wp-photos directory, but the post does not show up at all.

Every step I take shows me that the e-mail gets delivered to the address, the image copied, but the post does not take place.

As I have done research, it appears that it is a pixel issue and not an actual file size issue.

I have one image that is 522KB but has dimentions of 1075?—806. That image is copied to the wp-photos directory, and the post happens just fine.

My original image is 506KB and has a dimention of 2560?—1920. That image is copied to the wp-photos directory, but the post never happens.

Anyone have any idea how to fix this one? I am setting up the posting for a family member who is not very computer savy. I dona€?t want them to have to try to re-size their images, just so they can e-mail them.

I am currently running Word Press 1.5.2 and Postie 0.9.8.4. My php.ini has a memory limit of 80MB.

Thanks in advance.
