Hi Morten
We have reproduced the issue in later Dynamicweb versions. We have also found the setting on the image component that causes this and it is related to handling transparency and background colors of transparent source images.
We need a little time to sort out the issue though and to ensure we do not break transparency. It is registered as bug TFS#83876.
On a side note:
Today we release Dynamicweb 9.9 - in this version the image generation has been isolated in a provider - with a support for a new imaging provider using "Magic scaler" instead of imageglue. This can be enabled by exchanging the provider dll in the /bin folder.
Magic scaler has some advantages over the current implementation - more clear scaling, smaller images for espescially jpegs - and it is .NET core compatible. On the other hand it does not support the same amount of source formats (like psd and the likes). But it is great for 99% of the cases.
