Re: [Webtest] verifyImages don't likes .png images?

[David Koo]

Hi Avander,

This is probably due to the PNG being wrongly encoded somehow or perhaps
they are using some fancy PNG features that WebTest can't understand? I
would open the troublesome PNG in Photoshop or GIMP and compare the file
info (using the inspector) to a PNG file that does display (such as this
one: http://tuxpaint.org/stamps/stamps/animals/birds/cartoon/tux.png) and
then see what the difference is.

Also, try viewing the image with different browsers as the browser support
for PNG is quite variable (

)
