Hmmm… try to increase button's height <img src="style_emoticons//rolleyes.gif” style=”vertical-align:middle” emoid=”:roll:” border=”0″ alt=”rolleyes.gif” /> I tried the effect with PNG glyph, and all worked perfectly.
resize of the button and a png image didnt show any reflection, maybe serge got something to say about this unless there is another settings i should change in order for this to work
Maybe the reason in your case is, that you are using different imagelist than TsAlphaImageList. This property works only if the images are stored in a TsAlphaImageList! With other image lists like PNGImageList, it doesn't work for me also.
Reflections are supported completely if TsAlphaImagelist component is used or if Glyphs have 32-bit format (Bmp or Png). Other formats and ImageLists will support this property soon too.
