Remove GIF image background to match Original background in GWT? - image

So I have an image (GIF) with a blueish background and a circle (which i want to keep), I would like to remove the blueish background and ( or show the origin color of the back ground it sites on or make the background of the image totally transparent. )
Thank you .
This is GWT 1.6

GIF supports transparency also, open it in a image editor(not paint, it sucks) and select the background using the magic wand tool. Press delete and you're done!
PS: save it as GIF file if you have to..

This has nothing to do with GWT. The solution is to use PNG image format. PNGs allow you to specify a transparent background.

Inserted images into the report has grey background

When I'm inserting our company logo into Oracle Report there is a grey background on the logo. The logo is file type BMP, I have tried different file types like JPEG and TIFF as well. The issue still remains the grey background.
Below is the example of that grey background.
As you can see the portion which has the logo has a grey background whereas the background of the report is white. This is totally against our company guidelines and I've been told to find a solution for this. Please advise how can I remove the grey background.
Thanks
if you want to remove the background of the image then use an editing tool like photoshop and then remove the background and save the image as png then convert into bmp and then use it in your report.

nothing happens when I attempt to textout to a transparent image

I am using Lazarus.
I have put 2 images on a form and synchronized their positions and sizes.
I can textout to both images, and after I made the ontop image transparent I can see the combined content of both images.
I can add further text to the bottom image and see it, but I can't see text I try to add to the transparent image.
I used the following code to make the top image transparent
image2.picture.Bitmap.TransparentColor:=clWhite;
image2.transparent:=true;
I guess I need to play with the image bitmap, but I can't find a solution that is not using other software.
Can someone help me with this please?

photoshop saving image without white background

i can't remove the white background when saving as png or jpeg.
tried everything what suggested me on the web, but still get the diminsions i set up as whitebackground.
How can i save image without the background?
see image below for settings.
enter image description here
if you want to remove all the white from the picture, better go to color range and sample white. layer via cut and delete the layer. and save it in png as #cybernatic.nomad said, supports transparency.
Make sure you have created your image on a new layer and delete (or hide) the first white layer. I just created a simple text on a new layer with a transparent background and then loaded the image back into Photoshop to confirm that it works properly. As per previous comment I use .png format to preserve transparency.

Alternative to mix-blend-mode: multiply in Internet Explorer

On my site I have several hundred images in jpg format, with a white background area (in the image itself). This has worked fine as the html/body background was also white. Images appeared to be transparent that way.
Now, I am about to change the site theme and these same images will now have a light grey html/body background color. I have tried to use the css rule mix-blend-mode: multiply; to make the white areas in the images transparent. This works fine in Chrome and Firefox, but not in Internet Explorer (11).
Any suggestions on how to work around this? Just to be clear, it's not the image overall opacity I want to fix, it's only the white area in the jpg images that I want to make transparent.
If no solution is possible I will have to change the format to png or gif with transparency. That would take days to accomplish...

Layering images Love2d

I want to be able to layer images(PNG) with blank space over other images and have the images underneath still partly visible. right now my Image loading function will prints black space where it should have the background image.
As Noah mentioned, if your PNG images don't have an alpha channel, you can use LÖVE's blend modes.
https://love2d.org/wiki/BlendMode
Try displaying your image with "premultiplied", for instance.
love.graphics.setBlendMode("premultiplied")
love.graphics.draw(myImage)
love.graphics.setBlendMode("alpha")
"alpha" being the default blend mode.
