Texture pack help

[VanessaE]

As I mentioned in another post, I'm working on a texture pack, but I'm having trouble using/testing it. I've already scoured the web looking for hints as to what might be causing this problem, but I've come up short.


First, some background:

I started this project by getting a listing of filenames of every image supplied by Misa's 64x64 texture pack, since it supplies enough images to cover several popular mods.

From that list, I deleted the alternate tree since the images therein aren't needed here, and I deleted the nyancat images, since those are supposed to be low resolution pixel art (and Misa's images were of some other creature entirely). That left me with only a single folder containing 208 image files.

Culling from multiple freely-licensed and/or public domain sources and from my own work, I created replacements at 512x512 resolution for all of the above images, except for oerkki* and player*, which I haven't come up with replacements for yet, and treeprop, which is rendered to 1024x1024 (Misa's was rendered at 128x128).

After all the images had been created, I went back through the entire folder and made sure that those which take up the whole 512x512 frame (dirt, steel_block, etc.) are flat/opaque, while the rest (glass, torches, etc.)- have transparent areas as appropriate. Water, of course, is translucent.

All images were processed with The GIMP (and in some cases, rendered first with Inkscape), and saved out as png.

The problem:

When I put the texture pack to use, some images therein simply aren't being used, despite my having checked and re-checked everything I could think of.

For example, all of the dirt blocks with grass on top should be rendered with default_grass on the top side, default_grass_side (dirt+grass) for the four sides, and default_dirt for the bottom. Instead, I get grass on top and plain dirt on the sides, even though I've done nothing more than create a bunch of replacement image files.

Similarly, all of the ores - iron, coal, moreores_*, etc. - are being rendered using only my default_stone image on all sides, instead of the images I supplied for those ores.

I have not modified any of the program's data files. I do not supply any such data in my texture pack either - it's just a folder full of .png files plus my image credits textfile. I am certain the filenames are all correct.

The affected texture pack:

I would appreciate it if someone would download this, take a look, and tell me where I screwed up. :-)

Notes:
Some stuff is unfinished. Misa's player and oerkki graphics have been included here as placeholders, and will be replaced as soon as I can come up with suitable images.

See image-credits.txt for a list of links to all of the source imagery that came from the web.


EDIT:

I figured out the issue. Apparently, default_grass_side and all of the related *_ore images require an alpha channel, even if the images are otherwise solid/opaque. Here's the fixed version (at least, fixed what I've discovered so far):
