What's with all the errors?

trying to make sense of an influx of errors in error_log

[suga]

i've been seeing a huge influx in errors lately. most of the errors i am not able to recreate.

for instance, an error will occur on a page such as [mywebsite.com...]

when product-list.php loads, it loads images such as the ones located at /images/banner.gif

when i go to [mywebsite.com...] it loads fine, including images.

what i am seeing in my error_log, however, is that someone goes to that page and experiences an error when the php page tries to load /products/images/banner.gif. this is NOT the true location of the image, so why is the browser trying to find the image there?

do i have an issue with redirecting? if so, why can't i recreate it when going to the product-list.php page?

is this typical activity of a spider or bot? or do spiders only crawl pages that exist or are linked to either by me or by an external site?

thanks.
