Hello Steve

Thanks for the response, your sample application seems to respond in the same way as well(Samples/WebImageViewer/ImageViewerDatabinding.aspx?View=Run)

Thanks for your help.

Hi Rumen,

THanks for the help, I have submitted it as a bug so shall just hang tough (as they say in the films), most of my clients will be on IE so it's not the end of the world....

Just a quick follow-up - I see that indeed this is something caused by the rendering of WebImageViewer - in certain situations images are rendered with empty src tags, hence the effect you are seeing with hitting the page twice in FireFox.

I suggest contacting developer support with a link to this forum thread and submitting it as a bug - this way you will be entered as a notify person when the bug is resolved in a subsequent hotfix.

I hope that this is not a major showstopper for you in your project. 

I have seen a problem in FireFox requesting pages twice, for no apparent reason. It took me a lot of time to figure this out, but it appears that if you have images on the page with empty src tag, e.g.

<img src="">

This will cause FireFox to request the Html / ASPX page twice for reasons which are better described here:

Could you please check if this is the case? In this case, you may want to avoid that or place transparent images with 1px width/heigh as suggested in a workaround in one of the blog posts above. 

 Not that anyone seemed to have a vague interest, but it is due to Firefox i do my development and normally test in firefox as my default browser, I was reworking this problem and thought i would check IE, and it does not do the two postbacks! Spooky!
