So, I haven’t figured all of bp_core_fetch_avatar() out, but here’s some of the types:
type=thumb
type=full

Interestingly, the code I pasted in my previous post took the thumbnail image, but displayed it the size of the full (150×150 I think). So, it was pixelated and ugly. So, I changed it to type=full and it’s a nice 150×150 image.

If anyone else can explain the rest, this seems like some good content for the codex.

I’ve been trying to get it to pull various size group avatars and haven’t had much luck. Here’s the code I’m using:
$avatar = bp_core_fetch_avatar( array( ‘item_id’ => $group->id, ‘object’ => ‘group’, ‘type’ => $type, ‘avatar_dir’ => ‘group-avatars’, ‘alt’ => $alt, ‘css_id’ => $id, ‘class’ => $class, ‘width’ => $width, ‘height’ => $height ) );

Shouldn’t I just be able to pass the width and height values that I want? Am I only allowed to pass in certain width and height values? Seems like I could also pass in $type and that could give me the various sizes?

Also, this passes the full HTML for the image. Is there a way I could just get the URL of the image? I could rip it out of the HTML, but that’s kind of messy.

That’s a good point. Incase we want different size for groups and members the only good way is to override the “bp_core_avatar_handle_crop” and may be in extreme case “bp_core_avatar_handle_upload” and that will give you enormous flexibility.
After overriding it, we can filter on “bp_core_fetch_avatar” and that will be all we need.

@sbrajesh It seems like the group avatar’s use this same code. How would you call the bp_core_fetch_avatar of varying sizes for groups by group id?

well, The very first thing is
1. define the 2 size(bp allows only 3 sizes of avatar at this moment) using the constants BP_AVATAR_(THUMB/FULL/ORIGINAL_MAX)_HEIGHT and BP_AVATAR_(THUMB/FULL/ORIGINAL_MAX)_WIDTH if the original avatar sizes(50×50,150×150,450×450) does not fit your requirement.

Then use bp_core_fetch_avatar, it supports the width,height property and thumb type
You can fetch an avatar of different size using different width/height value but again, It will not crop, it will constrain the avar using the width/height property in the img tag. so i don’t think it will be of much use .

But if you want only 2 sizes of avatar, as you mentioned above, define one as Thumb,other as full and fetch thumb using “type=thumb” and the other using “type=anything other than thumb” in bp_core_fetch_avatar and it will work.

Ok, i’ve managed to do it with:
global $bp;
bp_core_fetch_avatar( array( ‘item_id’ => $id, ‘type’ => ‘full’, ‘width’ => ’75’, ‘height’ => ’75’, ‘html’ => ‘false’ ) )

If somebody needs the same thing he can try this lines, maybe it will help.

1.2.5 has an almost totally rewritten bp_core_fetch_avatar function that should fix these issues. Can you confirm that all files are up to date and try again?

The user_id argument doesn’t exist because there is no user_id argument. The argument that accepts a user id is the item_id argument as I stated above. Try this:

echo bp_core_fetch_avatar( array( ‘width’ => 30, ‘height’ => 30, ‘item_id’ => 1 ) );

If all you need is the thumbnail, then you don’t need the ‘type’ argument, as it defaults to thumbnail.

Have a look at bp_core_fetch_avatar(). It accepts a number of arguments you’ll want to explore for your use case. The most important being $item_id, which in your case would be your user id number and that user id of your teacher.
