Image Error Help

Hey guys, Im having a little trouble here, I own www.brakesint.co.uk and on the catalog i have just uploaded some product images, now on some of the machines (PC’s) in this building are showing a strange image, It is appearing yellow…

when on my machine it appears Correct like this…

But that image ^ (Correct) is fine on PC’s outside of our offices (for now - we havent had any reports and we have tested on a few external PCs), now we have looked into caching but that dosent seem to be the problem and the image that appears yellow also has the correct image behind it, but we have no idea where the yellow is coming from, the images are JPGs and are fine, their is absolutly no yellow of the type on the website nothing covering it at all, Does anyone have a clue to what this issue might be??

MANY Regards

Peter Bennett

EDIT: If your interested in searching the above part number go onto the flash catalog easier located at (www.brakes.org.uk) click shop online, then click the big green button and select the make (VAUXHALL) then at the bottom type “VECT” for vectra or just type it all in “VECTRA” and click search now choose the (02 - 1.8 & 2.2 16v models) and then choose the “Disc and Drums” option to the right and select “REARS” Then you should have BDS6001 and BDS6002 click (BDS6001 the thumbnail) and see the large picture, do you get the correct or INcorrect image??

Thanks Again

Pete
