U++ forum: Welcome to the forum

If you want a view something like this:
index.php?t=getfile&id=6717&private=0

One possibility is:

#include <GridCtrl/GridCtrl.h>

using namespace Upp;

#define IMAGEFILE "ImageGridCtrl/Icons.iml"
#define IMAGECLASS Images
#include <Draw/iml.h>

//from HomeBudget example
struct DispPM : GridDisplay
{
	virtual void Paint(Draw &w, int x, int y, int cx, int cy, const Value &val, dword style,
			           Color &fg, Color &bg, Font &fnt, bool found, int fs, int fe)
	{
		if (val==0)
			SetCenterImage(Images::one());
		else if (val==1)
			SetCenterImage(Images::two());
		else if (val==2)
			SetCenterImage(Images::three());
		else
			SetCenterImage(val);
		
		GridDisplay::Paint(w, x, y, cx, cy, Value(""), style, fg, bg, fnt, found, fs, fe);
	}
};


struct ImageGrid : TopWindow
{
	GridCtrl gr;
	ImageGrid() {

		gr.AddColumn("Images").SetDisplay(Single<DispPM>());
		
		for (int i = 0; i < 3; i++ )
		{
			gr.Add(i);
		}
		for (int i = 0; i < 10; i++ )
		{
			int r = Random(255);
			int g = Random(255);
			int b = Random(255);
			
			Image img = CreateImage(Size(64,64), Color(r, g, b));
			gr.Add(img);
		}
		
		Add(gr.SizePos());
	};
	~ImageGrid() {;};
};

GUI_APP_MAIN
{
	ImageGrid().Title("ImageGrid").Run();
}

Another possibility would be something like this:

gr.AddColumn("RichText").Ctrls<RichTextView>();

with a possible mini Uword Editor to add images and/or links.

Btw, for some reasons, I couldn't get to work this case:

gr.AddColumn("ImageCtrl").Ctrls<ImageCtrl>();

which seems the most logical to use...

P.S. I see you need some help with answering questions on forums?..

P.P.S. Also, imho, there is a bug in GridCtrl::Clear(columns=true)
missing line:

aliases.Remove(1, aliases.GetCount() - 1); //TODO Report a BUG?

because if you clear columns and then add columns in the same GridCtrl again, it accumulates/duplicates aliases, messes up indexes and crashes...
the whole method should be at least like this:

void GridCtrl::Clear(bool columns)
{
	doscroll = false;
	
	anchor = Null;

	UpdateCtrls(UC_HIDE | UC_CTRLS);

	int nrows = columns ? 1 : fixed_rows;
	items.Remove(nrows, items.GetCount() - nrows);
	vitems.Remove(nrows, vitems.GetCount() - nrows);

	total_rows = nrows;
	fixed_rows = nrows;

	if(columns)
	{
		hitems.Remove(1, hitems.GetCount() - 1);
		items[0].Remove(1, items[0].GetCount() - 1);
		rowbkp.Remove(1, rowbkp.GetCount() - 1);
		edits.Remove(1, edits.GetCount() - 1);
		sortOrder.Clear();
		total_cols = 1;
		total_width = 0;
		total_height = 0;
		firstCol = -1;
		lastCol = -1;
		fixed_cols = 1;
		coluid = 0;
		hcol = -1;
		sortCol = -1;
		genr_ctrls = 0;
		firstVisCol = fixed_cols;
		lastVisCol = total_cols - 1;
		
		aliases.Remove(1, aliases.GetCount() - 1); //TODO Report a BUG?
	}
	else
	{
		total_height = fixed_height;
	}

	firstVisRow = fixed_rows;
	lastVisRow = total_rows - 1;
	
	focused_ctrl = NULL;

	valid_cursor = false;

	firstRow = -1;
	lastRow = -1;

	curpos.x = curpos.y = -1;
	curid.x  = curid.y  = -1;

	hrow = -1;

	rowidx = -1;
	rowuid = 0;

	row_modified = 0;

	UpdateSizes();
	UpdateSb();
	
	if(ready)
	{
		UpdateHolder();
	
		oldpos.x = sbx;
		oldpos.y = sby;
	
		RebuildToolBar();
		Refresh();
	}

	WhenEmpty();
	WhenCursor();
	
	doscroll = true;
}
