Hi Jimmy, It looks like your calculation of tileY variable is always a multiple of 1000, that way tileY % 1000 always returns 0 I don;t have the data to dive into this more deeply

OpenLayers.Util.indexOf(this.serverResolutions, res) : this.map.getZoom(); /** * Zero-pad a positive integer. * number - {Int} * length - {Int} * * Returns: * {String} A zero-padded string */ function zeroPad(number, length) { number = String(number); var zeros = []; for(var i=0; i<length; ++i) { zeros.push('0'); } return zeros.join('').substring(0, length - number.length) + number; } var components = [ this.layername ]; var path = components.join('/'); var url = this.url; if (url instanceof Array) { url = this.selectUrl(path, url); } url = (url.charAt(url.length - 1) == '/') ? url : url + '/'; return url + path+"/"+this.layername+"_"+res+"_"+zeroPad((parseInt(tileY) % 1000), 4) + '.' + this.extension; } But OpenLayers get just the first tiles (0000.jpg) by zoom. Do you have an idea why openlayers take just one tiles? Cheers. Jim 2010/4/21 Kris Geusebroek <kgeusebr...@xebia.com<mailto:kgeusebr...@xebia.com>> Hi Jimmy, You can use a server to do that, but it is also possible if the tiles are served from a webserver. The directory structure or naming of the tiles has to be somewhat structured though. You can use the OpenLayers.Layer.TileCache class of openLayers if you confirm to that directory/naming convention or you can subclass that on and overide the getURL method to create an url that makes sense with your tiles. Hope this helps you a bit.

I tiled it and tiles are accessible. I would like to know if OpenLayers manage tiled images. I don't know if I'm clear.
