Can't make image background transparent
I searched for posts like this but found none. I am trying to make the background transparent on a jpg file.
- I have tried: Tools-Selection Tools-Foreground Select, Select-Invert, Layer-Transparency-Add Alpha Channel
But there is no box to select Foreground or background. There is only a box which says Foreground Select and under that, it says Preview Mask. Then I click on the background of the image and a point on the image is set and then I move the mouse and click it a second point is set and a line forms between the two points. And I have no idea how to make the channel clear.
- I also tried: Layer-Transparency-Subtract from Selection
But there is no option to select the background as is shown in the online help. So I'm left with my original image.
- I have also tried: Layer-New Layer
But all I get is a box that lets me choose options such as - Opacity and Fill With. I have chosen Fill With-Transparency and Opacity-both 100% and 0%. But it still doesn't make the background transparent.
Can someone tell me how to simply make the image background transparent? Thanks.
