I am having trouble making good transparent backgrounds on my images. These are just two color images, say like a butterfly on a white background. So I'm just trying to get the white background transparent. I have used GIMP, Photoshop Elements, Paint Shop Pro and they all leave smatterings of the white background when I'm done. I made sure to save in either .gif or .png format. I also have made sure Alpha Channel is selected (as required by GIMP). I must have watched 25 YouTube videos on each of the programs and followed them step-by-step very carefully. But when I upload the image that I made the background transparent, there are still several smatterings of the white background. I make sure I go over and over the whole background with the transparency tools to be sure I haven't missed any areas but they always end up with a bit white.

Have any of you found one of these products better than the others on doing this transparency thing or have any thoughts as to what I might be missing in this process - just seems like this shouldn't be this difficult. It has become very, very frustrating as I have spent hours trying to get just one image to turn out perfectly transparent after I upload it and view it on my web site.

Are you Replacing the white color background with the transparent color ? Some tools allow you to sample a color and replace it with another. If thats what you are doing, then the reason some 'white' is left over is because the white background is not entirely white, like different tones of white.

I'd suggest Photoshop Elements ... (I use an old Photoshop)
Copy to a new layer (CTRL+J) >> select only the new layer >> then Erase the background.

For "spatterings" ... I give them an outer glow or a stroke layer effect so I can see where they are.
Then manually erase them .... when done > remove the layer effects.
Sometimes it helps to Temporarily add a new lower layer > fill it with Black or a color so you can see the "spatterings" above.

Save as a png for the Butterfly ... (for all the 16m colors) ... gif only has 255 colors.

To manually erase in a line or a continuous line ... like an edge ...
Click then Ctrl +Click to connect the 2 clicks .... Ctrl+Click keeps connecting the clicks
Space Bar to temporarily call up the hand tool where the image can be zoomed or moved.
Zoom Way In ... improves the accuracy of the click positions.

What version of Elements ??? ...
It's probably the best to use when you get used to all "the tricks" .. (a.k.a. Keyboard Shortcuts)

My Left hand is usually as busy as my Mouse hand.
Transparency is not a color ... its the absence of anything .. (Nothing)

I've got Elements 18 - But don't use it.
Should be about the same as 10 .. I hope :D

All the tools are moved and renamed from PS, but it'll still do all I said.

Mostly ... I erase around the Border Manually .... then erase all outside ... (one click)
The trick is Pencil Erase >>> Zoom In for accuracy >>>
and click erase the perimeter of the "butterfly"

Start with >> Edit >> Preferences >> General ...
and set ... [Use Shift Key] ... and ... [Zoom with]

Can you attach a pic you want transparent ??

No more images right now but I might need your help in the future for one now and then. Anyway to reach you other than posting publicly here or if I just post on this topic you'll probably reply, right? When I 'save as' in .png format it asks if I want to save as Interlaced or Non-Interlaced. The default is Non-Interlaced, should I just leave it at the default? What tool do I use for a Stroke or Glow color so I can see if there are any spatterings and then I can go back a catch them before saving? Can't thank you enough!!! Hope you and yours have a great holiday and an even better New Year (y)

Posting on my reply "Here" will alert my Email.
I do a lot of Now-and-Thens
Not sure about Interlaced or Non-Interlaced ... I always default.

Styles > Strokes >>>
Layers >> (the little fx on the side of the layer) >>>
Click on the color and choose whatever color is a contrast >>> Red, Black

I tried with paintdotnet, background came out transparent & 'clean'.
Took longer to d/l & open than to remove background.

I have photoshop but havent used it in years.
What I do, paintdotnet works just fine, , , ,

This image is a gray color with a pure white background . I have worked for well over an hour using Photoshop Elements 10 using the Magic Eraser Tool. I went over and over the image with the magic background eraser tool and still have all these smatterings (see image below - I have circled in green the smatterings.) Saved it as a .png. must be doing something major wrong. When I get a chance I'll write to every single step I take when trying to make a white background on a image transparent and submit it up here for you all to look at. I don't see others posting here with this kind of problem. but I can be pretty dense some times.

Sometimes when I have spatterings .....
Using a magic wand setting of 255/contentious .. (255 = everything/connected)
I select the main Image (all of it) >>>
Invert the selection >>> (Select > Inverse) (for everything outside the selected image) >>>
and hit the Delete Key ... (Spatterings Gone)

All this depends on the main image not being connected to any of the spatterings.
If so, use the delete tool and break the link(s) first
