That's because when Imaging 0.26.0 was released current version of Lazarus was 0.9.24, but
in 0.9.26 they renamed TGraphic.GetDefaultMimeType method to TImagingGraphicForSave.GetMimeType.

You can either wait few days for Imaging 0.26.2 release (or get the source from SVN now) or
fix the few lines yourself (see this post http://galfar.vevb.net/imaging/smf/index.php/topic,88.msg303.html#msg303).

Hi,

How do I install Vampyre Imaging Library on lazarus 0.9.26.

From Pacakge>>Open Package File, I browse to C:\Documents and Settings\Arun John\Desktop\imaginglib0260\Imaging\Source\Projects,
here I select the .pak file, the Package dialog shows the list of files, I click on Install, the install starts, and soon stops with this error.. I have pasted below the copy of the compiler output...

Please help....

thanks
