Here is an example of simple image viewer I have made from the info and examples on this forum.

Feel free to make it complicated. regards, Algwat.

// sweep image viewer
File[] list; // Files, not Strings
//
PImage[] imgs ; // fn matched images
int Nimg = 0;
int sframes = 0;
int eframes = 0;
int nframes = 0;
int lprate = 15 ;
//String fnmatch = "20130812_18" ; // files matched to this string
String fnmatch = "20121012_" ; // files matched to this string
String fpath = "C:\\Users\\alan\\Documents\\Processing\\StereoRotator1\\data\\HI1B" ;
//String fpath = "F:\\Documents\\DMKALLSKY1\\data\\20130812meteor" ; // filepath to images
void setup() {
size(968, 720);
frameRate(lprate);
//
File dir = new File(dataPath(fpath));
list = dir.listFiles();
//
mloop() ; // match file names
//
ldloop(); // load matched files
//
}
void draw() {
background(0);
floop(); // show image loop
text("[ "+frameCount+" / "+nframes+" ][ FPS "+lprate+" ]", 500, 10 );
frameRate(lprate);
// g.removeCache(imgs); // do not remove this line
}
void floop() {
image(imgs[abs(frameCount)], 0, 0, width, height);
if (frameCount >= nframes-1) {
frameCount = -(nframes) ;
}
if (frameCount == -1) {
frameCount = 1 ;
}
}
void mloop() {
for ( Nimg = 0; Nimg < list.length ; Nimg++) {
//
String fn = list[Nimg].getAbsolutePath();
String[] m2 = match(fn, fnmatch );
if (m2 != null) {
eframes = Nimg ;
nframes++ ;
// println(list.length+" "+sframes+" "+eframes+" "+nframes+ "Match found in '" + list[Nimg] + "'\n"+fn);
}
else {
// This will print to the console, since no match was found.
sframes = (eframes - nframes) ;
// println(sframes+" "+eframes+" "+nframes+ "No match found in '" + list[Nimg] + "'\n"+fn);
}
}
}
void ldloop() {
// load matched images
imgs = new PImage[nframes];
for (int x = 1; x < nframes; x++)
{
imgs[x] = loadImage(list[(sframes+x)].getAbsolutePath());
print( x + " images loaded\n ") ;
}
}
void keyPressed() {
//
if (key =='x') {
exit();
}
if (key =='c') {
background(0);
}
if (key =='-') {
lprate=lprate-1 ;
if (lprate <= 0) {
lprate=1 ;
}
}
if (key =='=') {
lprate=lprate+1 ;
if (lprate >= 30) {
lprate= 30 ;
}
}
//
}
