Opacity watermark

Hi,
I can´t opacity water mark. See you images please.

Hi,
The problem is maybe coming from your template CSS, can you give me a link to your product page ? you'll probably be able to fix it with some CSS code.

Can you delete, and re-upload your product image ? Then your watermark opacity will be automatically applied.

Yes, I understand, but the problem is that the watermark is too dark.
Although you config 50% opacity or you create a image very clear.
Understand you?

Hi,

You use a watermark with some transparency, the opacity system in the GD library does not work well with it.
The best is to change the watermark image itself, by setting some transparency in the text itself.
