Ok the photo I posted above has a width of 1500px and yet on my browser it appears smaller but in proportion. I uploaded this photo and then used the bb code to display it. Gonna try with a large random photo from the internet next..
OK my conclusion is that for some reason this forum does not like displaying flickr photos!!! god knows why - and he's a regular viewer of this forum so maybe he'll wise us up! But seriously folks.. (you mean you were trying to be funny!?) I really don't know why there is a problem with flickr photos, however if the photo posted is no wider than 720ish px then I'm sure distortion won't occur. OK I've got work to do so I'd better leave this query for now, the solution has not yet been found but is under investigation Have a nice day!
