can seek next code

-(void) imagedownloader : (nsstring *)urlstringofimage { urlstringofimage = [urlstringofimage stringbyaddingpercentescapesusingencoding:nsasciistringencoding]; //or urlstringofimage = [urlstringofimage stringbyaddingpercentescapesusingencoding:nsutf8stringencoding]; // normal stuff doing. }

update

i think in case other method stringbyreplacingpercent rather stringbyaddingpercent should work, seek following

urlstringofimage = [urlstringofimage stringbyreplacingpercentescapesusingencoding:nsutf8stringencoding];

update2

the url gave not valid url see image, think should study webservice developer set valid url encoding, or improve alter webservice image urls, utilize of uniqueid or, something.
