Hi Anis, well most of the time bitmap editors will indicate transparency by having a kind of checkered looking background like this:



The above is a screenshot taken from Paint Shop Pro after loading the OffsetIcon.png file, notice the gray and white checkered background? That means it is transparent.

If you have only a solid white background then you will get a solid white color in the button as well just like you are showing.

So somehow you are doing some incorrect steps that loses the transparency.

One thing to make sure is that you save as PNG format, not JPG - JPG files do not support any transparency in them so saving as JPG would be one easy way to lose transparency information.

You may want to check online for some tutorials on bitmap manipulation stuff, for example there seem to be several video tutorials for photoshop if you search on google or youtube for "photoshop colorize" or similar type things.
