Icon IDs?

I've search for something about it for about 2 hours and found nothing...There was a script or command or something that would pull up all of my iconset.png image and would show me the icons and show me the ID for it because I don't know how to know the ID for item icons...

Well, it's just a counting exercise to determine the ID of an icon in the set. The numbering starts at 0 and goes from left to right, then down to the next row. There are 16 icons in each row, so it's really not that hard. Basically, it is the following:

0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
16	17	18	19	20	21	22	23	24	25	26	27	28	29	30	31
32	33	34	35	36	37	38	39	40	41	42	43	44	45	46	47
48	49	50	51	52	53	54	55	56	57	58	59	60	61	62	63
64	65	66	67	68	69	70	71	72	73	74	75	76	77	78	79

And so on. All you need to do is count down to see what row it is in, multiply that by 16, and then add by whichever column it's in. I personally find that counting is faster than test playing just to check an icon. However, to each his or her own.

The script you're thinking of is Woratana's IconViewer, which is included in his Christmas Giftbox.

I think Yanfly made one too, which could be found in Pockethouse Scripts.

I think there is a script in woras script box that does this.
